c++ - Contents of an untyped object copied into vector -

-

I am trying to write content of an intermediate object which keeps the images of an image in a vector filled with unsigned characters . Sadly, I can not get it to work, maybe someone can tell me in the right direction?

What's my time here: 

  vector & lt; Unsigned four & gt; SQLiteDB :: BlobData (int clmNum) {// I get data of image configuration zero * data = sqlite3_column_blob (pSQLiteConn-> pRes, clmNum); Vector & lt; Unsigned four & gt; Bytes; // Image size changes in bytes int size = matching (clone); Unsigned four b [size]; memcpy (b, data, size); For (int j = 0; j and lt; size, j ++) {bytes. Push_back (b [j]) m) return bytes; }   
 If I try to find the contents of the bytes vector then all this is empty.  
 The question is, how can I get data in vector?   
 
 
 You should use the vector constructor, which takes some of the rockers:  < Pre>  constant unsigned char * data = static_cast & lt; Kong unsigned letter * & gt; (Sqlite3_column_blob (pSQLiteConn-> pRes, clmNum)); Vector & lt; Unsigned four & gt; Bytes (data, data + matchingbites (clones));

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
